GEORGE it. EUKE is AND ROBERT n. Arron-insert, OF oHIcoPEs,MASSACHUSETTS.

To all whom it may concern.'

Be it known that we, GEORGE'R. EUKERS and ROB- ERT H. A'roHnsoN,citizens of thel United States of America, and residents of Chicopee, inthe county of Hampden and State of Massachusetts, have invented certainnew and useful Improvements in Tire-Coverings, of which the following isa full, clear', and exact description. l t

'lhis invention relates to improvements lin coverings ior vehicle wheeltire-s and more particularly available on the pneumatic tires used onautomobiles.

The object of the invention is to provide an armored covering for thepneumatic tires which while eiicient land reliable for the protection ofthe tire against puncturing is extremely flexible, and without tendencyto impair theresiliency of the tire.

with another thereof transversely thercbeyond, said tubes being providedin such number and proximate arrangement as to constitute a lexiblcmetallic tread and prt'ltective portion for the appliance. This tirecovering may be used over the ordinary outer shoe, t.;- ing madeseparately tlicreirom and retained in` place thereon by the intl-ationoi the tire and the expansion of the outer shoe or it .may be made as apart of the outer shoe.

The iml'irovedtire covering or armor is illustrated in theaeconii'ianying drawings in which,-

.Figure l is a side elevation of a vehicle wheel having the in'qirovedcovering thereon, witlrsome parts broken away, and som:- parts omitted.ltig. .2 is a cross sectional view ol' the covering in place aboutthe-shoe of a pneumatic tire. Fig. 3 is a perspective view Of one of thelink-tubes. Fig. -1 is a perspective view showing a fragriient oi thecovering. ltig. 5 is a' perspective diagram showing the convolutions .ofthe band or cable which makes the body of the tire covering andillustrating splicings between the outer opposite coils and thc coilsnext therewithin. l

Similar characters oi reference indicate corresponding parts in all ofthe views. i In the dra\\'ings,i\represents a plurality of circularlycoursed bands preferably constituted by the successive coils of a singlewire cable., the coils being arranged quite closely together andconforming to the shape ei' an annular trough, as represented moreparticularly in Fig. 2,---tl1e intermediate coils being larger than theouter coils which gradually diminish in their diameters whereby thetrough form of the structure is acquired. The terminals of the outer andoppositely located coilsarc united to the coils next thereto andthercwitliin by splicings indicated at a in Figs. l and 5.

-TIRE -COVERING.

Patented Oct. 8, 1907.

Metallic flattened tube links b are provided in repeated series, thevarious tube link series having alternated arrangements relatively toeach other whereby those of one series engage with and connect toadjacent coils A while the relatively intermediate links of eachsucceeding series engage but one of rthe pair of coils connected bythefirst given link series, and engage and connect a still further sidewiselocated one o i the coils. This may be definitely perceived andunderstood on reference to the drawings, Figs. l and 4,-.-onerepresenting for instance the first coil, 2 the second and 3 the thirdcoil, and so on. .The links 12 in the first series encircle and connectthe sidewise adjacent coils l and 2, while the links -23 have theirlocations transversely offset, so as to lbreak joints7 with the links l2l2, and intermediate of which the links 23' have their places, saidlinks 23 of the second series encircling and connecting the second andthird coils, this offsetting oi' the alternated links ofthe successiveseries thereof being Observed throughout the entire structure.

In the fabrication oi the covering, the coils are suc- I anddiagrammatically represented in Fig. 5 with the size of the`convolutions gradually increasing from the lside to the middle; thetubular links, which arc preferably endless, being combined and engagedwith the pairs of coils as they are successively formed, the splicings aatthe terminals ol' the Outer coils being made last. Such of the linktubes as are employed at intervals at the tread portion of the tirecovering are provided with calks or projections bg, as indicated inFigs.

l and 3 for imparting slip preventing capabilities to the appliance.

1. A tire covering consisting ot' a body comprising `a plurality olfcircularly coursed bands arranged to' conform to the shape of anannular' trough, and a multiplicity of metallic link-tubes engaged withand connectingV each of said bands with another thereof which is tranorsely therebeyond, said tubes being provided in such number and havingsuch proximate arrangement: as to produce a lievi ble metallic tread and'protective portion for the appliance. 2. ln a tire covering a bodyconsistincr or' a cable Formed into a plurality of coils conformed tothe shape oi' an an- Iserps engage withand connect sidewise adjacent:coils,

while the r atlvely intermediate links of each succeeding series engagebut one of the pair ol' coils connected by. the first link s ries, andengage and connect a still .further` sdewisc located one ot' the coils.

4g. [n a tire covering, :l body consisting ol' a single cable formedinto a plurality ot coils'conformed to the shape ol' an annulaitrough,and having the terminals ol' the outer and'oppositely. located coilsunited to the respective coils next thereto, and therewithiri, and amultiplicity of ,metailic link-tubes engaged With and Jconnecting eachof said coils with another thereof which is transversely there` beyond,and constituting a protective exterior to the ilexiandvproximatearrangement as to eonstitute'a flexible' metallicexterior for theappliance.

6. A tire covering consisting of a body comprising a plurality ofcircularly coursed bands conformed; to the shape of an annular trough,,and a multiplicity of metallic 'ties engaged with each of 'saidbandsland connecting'` it with another transversely located relativelythereto, and -v said tiescove'riug the -bands and constituting atiexi'ble 1 metallic exterior for the'appliance.

7. A tlreycovering consisting of a body comprising n.

plurality' of 'crcularlyroursed bands conformed -to the shape of anannular trou'glnand a multiplicity of metallic ties engaged 'with eachof Vsaid bands and connecting it ,with another transversely locatedrelatively thereto, said ties covering the bands and constituting a'flexible metallic exterior for th'ezappliance, and certain of saidmetallic ties at the tre'l portion of the tire covering havingcalks orprojections.

8. An armor composed of a series of tubes sind strands onwhieh the tubesare strung.

9. An armor foi-cushion and like tires, comprising circumferentialiyarranged rows of tubes flexibly connected. 10. A exible armor for tirescomposed of a series of short metallic tubes flexibly connected` 1 i1,1.
